Abstract

A catheter is presented having a planar end effector with elongated ablation electrodes configured to provide electrical signals to achieve IRE in target tissue. The planar end effector can be aligned along a longitudinal axis of a shaft of the catheter and configured to flex away from the longitudinal axis when making contact with tissue. Bipolar electrical signals can be applied between the elongated ablation electrodes in various pair combinations to achieve PFA. The end effector may also include diagnostic electrodes configured to receive electrical signals from tissue to map tissue, pairs of tissue contact electrodes to determine which portions of the end effector are in contact with tissue, or reference electrodes configured to measure blood voltage.
